As long as support for the "URL fopen wrapper" is enabled when you 
configure PHP (as it is by default) and set allow_url_fopen in the 
php.ini you can open files by http/ftp protocols and test their 
existence with the $file file pointer. 
eg.
  $file = fopen ("http://www.php.net/", "r");
  if (!$file) {
    echo "<p>Unable to open remote file.\n";
    exit;
  }
